Zenker diverticulum

Herniation of the mucous membrane of the esophagus through a defect in the wall of the esophagus. It is usually located in the posterior hypopharyngeal wall. Small diverticuli are asymptomatic. Large ones trap food and may cause esophageal obstruction, dysphagia, or the regurgitation of food. Treatment is by surgery or endoscopy.

Among the conditions addressed are laryngospasm, rheumatoid arthritis, schizophrenia, postpolio syndrome, tetanus, toxic caustic ingestion, Wallenberg syndrome, West Nile virus, Wilson disease, and Zenker diverticulum, among many others.
Computed tomography (CT) and a barium swallow showed an air-fluid level in a left-sided Zenker diverticulum (ZD) measuring 12 x 8.3 cm, extending from the C3-C4 intervertebral space to mid-T3 level and displacing the trachea to the right (figures 1 and 2).
In this case, the finding of the Zenker diverticulum was misleading.
A barium swallow was obtained (figure 1), which revealed a proximal diverticulum that did not appear like a typical Zenker diverticulum. The patient was taken to the operating room for endoscopic diverticulotomy.
A chest x-ray revealed evidence of aspiration pneumonia and a large mediastinal mass with an air-fluid level that caused anterior tracheal deviation, consistent with a possible Zenker diverticulum (ZD).
The incidence of Zenker diverticulum is at least four times greater than the incidence of K-J diverticulum.
